'data' is not defined when using REST Input

[RicePatrick]

When creating a new pipeline using the REST Input stage, attempting to run the pipeline or use the generated python code results in a 'data' is not defined error.

This appears to be a result of the fact that the data frame that's established uses a hardcoded variable name instead of the ${outputName}_data that is actually initialized by reading in the json.

I believe that the bug is present in both if blocks here: https://github.com/amphi-ai/amphi-etl/blob/main/jupyterlab-amphi/packages/pipeline-components-core/src/components/inputs/cloud/RestInput.tsx#L72

Steps to reproduce:

• Spin up a new Jupyterlabs docker image and install amphi
• Create a new pipeline
• Add a Rest Input step, and add any REST URL as the URL
• Run pipeline
